P(A) is the power set of A. If you don't know what that means, don't guess on the question, because you won't answer properly.

Third Question:

Very tricky math! Note: This must be done in your head only.

Do NOT use paper and pencil or a calculator. Try it.



Take 1000 and add 40 to it. Now add another 1000. Now add 30..add another
1000. Now add 20. Now add another 1000. Now add 10.


What is the total? Did you get 5000?

I was told that you could be paid by the power companies to generate power, connect it to their grid, and they just send you a check at the end of each month. So long as you can keep the wind or water turbines turning and don't use more power than they produce you get paid that is. If you were very motivated you could even connect a bike to a belt system and do it that way. The companies were supposed to have a program setup for this and I'd like to be able to get in on it if anyone has heard of, or uses this system and thinks it is also a good idea.

I am working on a simple video game. I want to incorporate 3d sound, but only through headphones. There's this type of recording called holophonic sound. I did research and found out that a special extra signal gets added to a sound to make it seem to come from a certain place. Since this signal is different for different angles, but not different when you record multiple times from the same angle, then there must be some sort of algorithm in making the added signal. Does anyone know how do i make this stignal or what exactly makes this signal?

Their reasoning was if we could fake it for the TV show, it's just proof we could've faked it for the "real" moon landing. What can I say to them to point out how ridiculous that is?

here is a diagram of the circuit.

I need to generate an input file or netlist to show the thevenin equivalent from the terminals x and x'. Would i add a voltage source in circuit with 0V to create a short but, i have no idea where to put it. Can anyone generate the input for simulation for me. Thanks

I am trying to help my daughter with her homework. I know the rule of a negitive number and a negitive number makes a positive.
OK, I need someone to explain in very simple terms, why is a negitive # +/- another negitive # a positive number? Why is it I can't have a -12 +-10= -22 or even -2?
If at all possible, can someone explain this graphically as I learn better that way.
